Antivirus software is a program designed to detect, prevent, and remove malware, including viruses, worms, and trojan horses, from computers and other devices.

Yes, if you use the internet or connect external devices to your computer, antivirus software can help protect against malicious attacks and data breaches.

Antivirus software can protect against various types of malware, including viruses, worms, trojans, ransomware, spyware, adware, and more.

Antivirus software uses a combination of signature-based detection (identifying known threats), heuristic analysis (detecting unknown threats based on behavior), and real-time protection (monitoring system activity).

Free antivirus software can provide basic protection, but it may lack advanced features found in paid versions, such as real-time protection, firewall, and customer support.

It’s essential to keep your antivirus software updated regularly, as updates often include new virus definitions and security patches. Most software can be set to update automatically.

Some antivirus programs can impact system performance, especially during scans. However, many modern antivirus solutions are designed to minimize this effect.

Follow the software’s instructions to quarantine or remove the detected threat. You may also want to run a full system scan to ensure your device is clean.

It’s generally not recommended to run multiple antivirus programs simultaneously, as they can conflict with each other and cause system instability.

In addition to antivirus software, consider using a firewall, keeping your operating system and software updated, being cautious with email attachments and downloads, and using strong, unique passwords.
